PRECODING METHOD AND APPARATUS FOR HETEROGENEOUS NETWORK COORDINATED MULTI-POINT TRANSMISSION

摘要

Embodiments of the present invention disclose a precoding method and an apparatus for heterogeneous network coordinated multi-point transmission. The method includes the following steps: obtaining parameter information of the heterogeneous network coordinated multi-point transmission system; comparing a first channel space transmitting power with the maximum transmitting power of a macro base station, and comparing a second channel space transmitting power with the maximum transmitting power of a micro base station according to the parameter information to obtain a comparison result; determining an obtaining manner of a precoding vector according to the comparison result, and obtaining a first precoding vector according to the obtaining manner of the precoding vector; and configuring the macro base station and the micro base station according to the first precoding vector. The present invention is applicable to a heterogeneous network coordinated multi-point transmission environment.
